Mapping Service Module

Mapping Service Module

The Mapping Service Module manages requests to preview data and run mappings.
The following table lists the requests that the Mapping Service Module manages from the different client tools:
Request
Client Tools
Preview source or transformation data based on mapping logic.
Developer tool
Analyst tool
Run a mapping.
Developer tool
Run a mapping in a deployed application.
Command line
Preview an SQL data service.
Developer tool
Preview a web service operation mapping.
Developer tool
Sample third-party client tools include SQL SQuirreL Client, DBClient, and MySQL ODBC Client.
When you preview or run a mapping, the client tool sends the request and the mapping to the Data Integration Service. The Mapping Service Module sends the mapping to the LDTM for optimization and compilation. The LDTM passes the compiled mapping to a DTM instance, which generates the preview data or runs the mapping.
When you preview data contained in an SQL data service in the Developer tool, the Developer tool sends the request to the Data Integration Service. The Mapping Service Module sends the SQL statement to the LDTM for optimization and compilation. The LDTM passes the compiled SQL statement to a DTM instance, which runs the SQL statement and generates the preview data.
When you preview a web service operation mapping in the Developer tool, the Developer tool sends the request to the Data Integration Service. The Mapping Service Module sends the operation mapping to the LDTM for optimization and compilation. The LDTM passes the compiled operation mapping to a DTM instance, which runs the operation mapping and generates the preview data.
